Meross Smart Temperature and Humidity Sensor MS100F

A temperature and humidity sensor for one room. It runs on room light through the solar cell on its front, with a CR2477 coin battery as backup, and reports to the Meross app through the Meross Smart Wi-Fi Hub (MSH300), which is sold separately.

Through the hub it works with Amazon Alexa, Google Assistant and SmartThings, and with Apple Home when the hub is the HomeKit version (MSH300HK). The app keeps two years of readings, which you can export.
